Sarah Meeham blends coffee for tasty-delight. she needs to prepare 130 pounds of blended coffee beans selling
for $5.38 per pound. she plans to do this by blending together a high-quality bean costing $6.25 per pound
and a cheaper bean at $2.50 per pound. to the nearest pound,
find how much high-quality coffee bean and how much cheaper coffee bean she should blend.
~~~~~~~~~~~~~
let x = amt of high-quality bean to blend
130-x = amt of cheaper bean to blend
6.25x + 2.50(130-x) = 5.38*130
x = = 99.84.
amt of high-quality bean to blend = 99.84 lbs
amt of cheaper bean to blend = 130-99.84 = 30.16 lbs
